Comparative evaluation of anxiety level, comfort, and time taken using digital and conventional impression techniques among pediatric population aged 8–12 years: A cross-over randomized controlled study

Abstract

Background A strong gag reflex could make it difficult for patients to accept and get dental care. Orthodontic models are needed for the diagnosis and treatment planning of occlusion and space management. Digital impressions can help to eliminate certain disadvantages, especially in children. Aim To compare the anxiety, comfort, and time required to record digital and alginate impressions in children (8–12 years). Materials and Methods A sample size of 30 was estimated and allocated into two groups. Group A: Alginate impressions were recorded on day 1. Group B: The digital impressions were recorded on day 1. Dave’s Hand Gesture Scale was given to measure the anxiety. After 7 days, the impressions of Group A were recorded using digital technique, whereas alginate impressions were recorded of children under Group B. The intraoral and overall time was recorded for both the impression techniques. Finally, a questionnaire was given to all the children to evaluate their comfort and preferences. Results The data were analyzed with SPSS software version 20.0 and used Chi-square analysis and Student’s t-tests where a significance value <0.05 was considered. The intraoral and overall time was less in digital impressions, and anxiety and comfort were found more in alginate impressions than digital impressions. Conclusion Digital impressions were recorded faster than alginate. When the anxiety was assessed, the digital impressions were considered to be more comfortable than the alginate methods.
